Install tooling & training
- Tool
- Cherry Maxibolt installation tool (hand or pneumatic)
- Special / proprietary
- Special tooling · proprietary
- Training
- Specialty; tool-specific for preload control.
- Inspection
- Stem flush-fracture; protrusion; visual lock.
Push-pull tool forms an extended grip range with a flush-breaking stem; the Ti variant uses a shift-washer for composite clamp-up.
Sourcing
Lead-time risk: Medium — Well-stocked structural bolt; Ti variant longer lead.
